Question:
This problem examines the Rankine heat engine introduced in Figure 5-5. Saturated steam at T = 250°C enters the turbine and the condenser operates at T = 40°C.
A. Assuming the turbine is reversible, give your best estimate of the efficiency of the cycle, and indicate the quality of the stream leaving the turbine.
B. Assuming the turbine has an efficiency of 75%, give your best estimate of the efficiency of the cycle, and indicate the quality of the stream leaving the turbine.
C. Find the flow rate of circulating water needed to produce a net power of 1 MW from the cycle with the turbine efficiency of 75%.

I believe everyone should try to be strong at logic and have good reading habit. Because If you possess these two skills, no matter what difficult situation is, you will definitely find a perfect solution out of it. While logical ability gives you to understand complex problems and concepts quite easily, reading habit gives you an open mind and holistic approach to see much bigger picture.
So guys, I always try to explain any concept keeping these two points in my mind. So that you will never forget any more importantly get bored.
Last but not the least, I am finance enthusiast. Big fan of Warren buffet for long term focus investing approach. On the same side derivatives is the segment I possess expertise.
